Abstract
The helium double-photoionization cross section has been evaluated using a Hylleraas wave function for the ground state in order to include correlation between the atomic electrons more directly than in previous calculations. Good agreement is found between the present results, the experimental data, and the theoretical work of Byron and Joachain. An interpretation of the differential electron spectrum is used to motivate an asymptotic calculation of the double-photoionization cross section which agrees well with the more exact treatment at high energies.Keywords
